What needs replacing?
Start with what you want to change.
New windows
Choose how each room opens and ventilates first. Casement, flush and sliding sash windows offer different frame lines and opening styles; uPVC and aluminium give you different finishes.
View new windowsNew doors
A front entrance needs a different layout from a wide garden opening. Compare composite entrance doors, paired French doors, bifolds and sliding doors around the space you use.

If your frames are sound and the glass has misted between the panes, we can assess the sealed units on their own. Send a photograph of the whole window and a close-up of the glass.

Oldbrook homes, and what to check first.
The homes. Oldbrook sits beside Central Milton Keynes and was built from the late 1970s, with terraces, semis, flats and housing association homes along its redways.
What that means. The houses here are usually straight replacements. Flats and shared buildings follow different rules, and the landlord or management company often has a say in what is fitted.
Check first. If you own a flat or a shared-ownership home, find out who is responsible for the windows before you get quotes. In many leases it is not the occupier.

Buying double glazing in Oldbrook.
Product choices, pricing and what happens before we fit.
Can you replace the glass and keep my existing frames?
We can replace sealed glass units in suitable existing frames. Send us photographs and approximate sizes so we can check the frame condition and identify the glass. For handles, hinges or locks, our repairs team can advise separately.
How do I get a price for double glazing?
Build your price online using approximate sizes, or book a free consultation and we price the job with you. Both use the same software and price list. Once you decide to go ahead, a technical survey confirms the measurements and fitting details before anything is made.
Do you supply and fit in Oldbrook?
Yes. We cover Oldbrook and its MK6 postcodes from our Milton Keynes base, and everyone who surveys and fits works for us. Nearby, we also fit double glazing in Furzton, Shenley Church End, Great Linford and Monkston.
Do I need permission to replace windows and doors in Oldbrook?
Most Oldbrook houses can have windows and doors replaced like for like without planning permission. For flats and leasehold or shared-ownership homes, the freeholder or housing association usually has to agree first.

We have used Fensters for years on a variety of glazing work, and 2 door installations. They are competitively priced and responsive. They take great care over measuring and specifying the work, giving you a clear quote so you understand what you are getting (thanks Perry!). The fitters are all extremely competent and personable. We had to replace our front door for accessibility reasons, they gave us confidence that our requirements would be met, reproduced the intricate leaded and stained-glass pattern of our old door, and did a quality fitting job (thanks to Johnnie and Shane!). In summary they are our go-to suppliers for all replacement and repair work.
